Engine Descriptions
The engines described in this publication are the 3408C and 3412C Industrial Diesel Engines. They are designed primarily for agricultural, petroleum, and auxiliary applications.A mechanical governor controls the fuel injection pump output, maintaining the engine rpm selected by the operator. Individual injection pumps (one for each cylinder) meter and pump fuel under high pressure to injection nozzles. Automatic timing advance provides the best fuel injection timing over the full range of engine speed.The fuel ratio control is located on the governor. The fuel ratio control restricts the fuel rack movement. Only the proper amount of fuel is allowed to be injected into the cylinders during acceleration. This minimizes exhaust smoke.Inlet air is filtered by an air cleaner. The air is compressed by a turbocharger before the air enters the engine cylinders. The turbocharger is driven by engine exhaust. The engines can be turbocharged, or turbocharged with jacket water aftercooling.The engines are four cycle engines. Each cylinder head has two inlet valves and two exhaust valves. The rocker arms and the valves are actuated by the camshaft. The action is performed by mechanical lifters and push rods.The cooling system consists of:* two thermostats (one for each bank) to regulate water temperature.* a gear driven centrifugal pump.* an oil cooler, and* a radiator (incorporating a shunt system).The engine lubricating oil, which is both cooled and filtered, is supplied by a gear-type pump. Bypass valves provide unrestricted flow of lubrication oil to the engine parts if oil viscosity is high, or if the oil cooler or the oil filter elements become plugged.Engine efficiency, efficiency of emission controls, and engine performance depend on adherence to proper operation and maintenance recommendations. Engine performance and efficiency also depend on the use of recommended coolant/antifreeze, fuels, and lubrication oils. Follow the recommended Maintenance Schedule found in this publication, paying attention to emission related components, air cleaner, oil, oil filter, fuel and fuel filter maintenance.
